18″ Rib-It-Ball Heavy Duty Insert
The PVC bladder insert for our Rib-It-Balls is a great choice for children with latex allergies. These bladders are a little heavier than our balloon inserts but they will withstand even the toughest of play and playground activities. Although very strong, the ball is intended for throwing, catching, and general play activities. We do not recommend that children be allowed to sit or stand on the ball.
